The best articles about processor tech I've found are at http://www.arstechnica.com. Look around a bit, they have an analysis of the IA-64 (Itanium), AMD K7, and a comparitive analysis of the G4+ and The Pentium 4. It left me slightly more respectful of the P4, if they hadn't ruined it with their push for clockspeed it could have been a really speedy chip (however, they did ruin it). Also, the Itanium is awesome. I realize that the current ones have a lot of problems, but the concepts and technologies they're going for are *awesome*. Let's hope Motorola uses some of them in the G5.
